Charles Xavier: Shaw's declared war on mankind on all of us, he has to be stopped.

Erik Lensherr: I am not gonna stop Shaw, I am gonna kill him. Do you have it in you to allow that?

- [Erik pauses while Charles shifts in his chair uneasy ]

Erik Lensherr: You known all along why I was here Charles, but things have changed. What started as a covert of mission, tomorrow mankind will know mutants exist. Shaw, us, they won't differentiate. They'll fear us. And that fear will turn to hatred.

Charles Xavier: Not if we stop a war, not if we can prevent Shaw, not if we risk our lives doing so.

Charles Xavier: There is so much more to you than you know. Not just pain and anger. There is good, too. I felt it. When you can access all of that, you will possess a power no one can match. Not even me.

Erik Lensherr: [Erik speaks apologetically towards Charles]
Us turning on each other, it's what they want. I tired to warn you, Charles. I want you by my side. We're brothers, you and I. All of together, protecting each other. We want the same thing.

Charles Xavier: Heterochromia was in reference to your eyes which I have to say are stunning. One green, one blue. It's a mutation. It's a very groovy mutation. I've got news for you, Amy. You are a mutant.

Co-Ed: First you proposition a girl, then you call her deformed. How is that seduction technique working for you?

Charles Xavier: I'll tell you in the morning. No, seriously, you mustn't knock it. Mutation took us from single-celled organisms to being the dominant form of reproductive life on this planet. Infinite forms of variation with each generation, all through mutation.

Erik Lensherr: [Shaw's mind is frozen by Charles]
If you're in there, I'd like you to know that I agree with every word you said. We are the future. But, unfortunately, you killed my mother. This is what we're gonna do.

Nux: [to Raven]
You got to see this. Your genes are extraordinary, you know that? Your cells ages at the half the rate of a normal human. When you're forty, you'll still have the leukocytes of a teenager. You have the most incredible cell structure I've ever seen.

Erik Lensherr: [stops the cab meter]
That would give us plenty of time to talk.

Charles Xavier: [to Eric]
There's so much more to you than you know, not just pain and anger. There's good in you too, and you can harness all that. You have a power that no one can match, not even me.

Toast: [Erik gives Angel a big tip]
For that, daddy-o, you get a private dance.

Charles Xavier: I can't stop thinking about the others out there, all those mind that I touched. I could feel them, their isolation, their hopes, their ambitions. I tell you we can start something incredible, Erik. We can help them.

Erik Lensherr: Can we? Identification, that's how it starts. And ends with being rounded up, experimented on and eliminated.

Charles Xavier: Not this time. We have common enemies, Shaw, the Russians. They need us.

- [Beast reacts with disgust, Erik gestures at Azazel and they vanish ]

Charles Xavier: Mutation. It is the key to our evolution. It is how we have evolved from a single-cell organism into the dominant species on the planet. This process is slow, normally taking thousands and thousands of years. But every few millennia evolution leaps forward.

Charles Xavier: Heterochromia is in reference to your eyes, which I have to say are stunning. One green, one blue. It's a mutation. It's a very groovy mutation. I've got news for you, Amy. You are a mutant.

Co-Ed: First you proposition a girl and then you call her deformed. How is that seduction technique working for you?

Charles Xavier: Sometimes. But we've talked about this, Raven. A small slip up is one thing. A big one does not bear thinking about it.

Sebastian Shaw: Erik, what a pleasant surprise. So good to see you again. May I ask you something? Why are you on their side? Why fight for a doomed race who will hunt us down as soon as they realize their reign is coming to an end? I'm sorry for what happened in the camps. I truly am. But everything I did, I did for you. To unlock your power. To make you embrace it. You've come a long way from bending gates. I'm so proud of you. And you're just starting to scratch the surface. Think of how much further we could go, together. I don't want to hurt you, Erik. I never did. I want to help you. This is our time. Our age. We are the future of the human race. You and me, son. This world could be ours.

Erik Lensherr: Everything you did make me stronger. It made me the weapon I am today. It's the truth. I've known it all along. You are my creator.

- [Shaw shoots Magneto's mother, which enrages him enough crush metal all around him ]

Sebastian Shaw: Outstanding, Erik. So we unlock your gift with anger. Anger and pain. You and me... we're going to have a lot of fun together.

Charles Xavier: To Homo neanderthalensis, his mutant cousin, Homo sapiens, was an aberration. Peaceful cohabitation, if it ever existed, was short-lived. Records show, without exception, that the arrival of the mutated human species in any region was followed by the immediate extinction of their less-evolved kin.

Charles Xavier: Don't kid yourself, you needed my help last night, it's not just me you are walking away from. Here you have the chance to be part of something much bigger than yourself. I won't stop you leaving. I could, but I won't.
